Today we started our block on cell reproduction. This will lead us directly into genetics and then evolution as we move forward. Next week we will dive into mitosis and meiosis.
For homework this week please do (and study) the following questions. Remember, much of the following will be on next week's quiz. However, any past quiz questions are fair game, so study all your old flash cards and quizzes. It's been a while since we've seen those prefixes and suffixes so they are due to make a return visit as well.
1. What is a vesicle and what does it do?
2. What does RNA polymerase do?
3. What does DNA polymerase do?
4. What is exocytosis?
5. What is endocytosis?
6. What is phagocytosis?
7. What is pinocytosis?
8. Would leaving the front do open so that flies can come in and out of the house at will be passive transport or active transport?
9. Would kicking someone out of your house because he ate all the potato chips be active transport or passive transport?
10. Is phagocytosis a from of endocytosis or exocytosis?
11. What are the 3 steps of the cell life cycle (just interphase)?
12. What happens during each step?
13. Why is the S step important? In other words, what does it prepare the cell to do?
14. What is the meaning of diploid?
15. What is the meaning of haploid?
16. Draw a picture and label the centromere and the sister chromatid.
17. What is a chromatid?
18. What is a chromosome?
19. What is the difference between a chromatid and a chromosome?
20. What is a somatic cell? Are they diploid or haploid?
21. What is a gamete cell? Are they diploid or haploid?
22. Which bio molecule is best for quick energy?
23. What kind of molecule is a triglyceride and what does it do?
24. In which bio molecule would you find nitrogen atoms?
25. In which 2 bio molecules would you find a carboxyl?
26. So in the cell we have transcription and translation and then the proteins wander into the rough E.R. or the Golgi body. Now that they are all formed and trained, what do they do next? In other words, what are their jobs?
27. What does a lysosome do?
28. What's the difference between a vacuole and a vesicle?
Answers:
1. A vesicle is a "bubble" of lipid molecules that transfers materials into, out of, and around the cell.
2. It splits the DNA to make mRNA.
3. It splits DNA to make an identical copy of the DNA.
4. Getting things out of the cell.
5. Getting things into the cell.
6. Trapping and taking large particles into the cell.
7. Trapping and taking small particles into the cell.
8. Passive
9. Active
10. Endocytosis
11. G1 S and G2. Or, Gap 1, Synthesis and Gap 2
12. Gap 1 - Cell grows, makes proteins and does whatever job that cell is destined to do.
Synthesis - makes a full copy of all its DNA
Gap 2 - continues to do its job but also prepares to duplicate itself.
13. Synthesis is important because it creates a copy of the DNA that will be passed on to the bouncing baby new cell when the cell splits.
14. Having two sets of chromosomes.
15. Having one set of chromosomes.
16. See your notes.
17. A coiled DNA molecule.
18. A DNA molecule.
19. They are the same thing but one is coiled.
20. A body cell. Basically every single cell except for a gamete. They are diploid.
21. A sex cell/gamete. They are haploid.
22. Carbohydrate
23. It is a lipid and it is the basic molecule for storing energy.
24. Protein AND Nucleic acids.
25. Lipids and proteins.
26. ATHENS. Antibodies, Transport, Hormones, Enzymes, Nutrition, Structure.
27. It recycles cell parts that are no longer needed so that they can be used again.
28. A vacuole is an "empty" part of a cell that can be used to store waste or materials. In a plant cell, it is used to take up space. A vesicle is a bubble made of lipids to transport materials in, out and around a cell.
